Oconee County, SC Fence Regulations: Height Limits (2026)

Rather than a single front/side/rear fence height number, Oconee County's zoning design standards regulate fence height specifically where it could block sightlines. Chapter 38, Appendix A(e)(15) states that no fence, building, wall or other structure (excepting single trunk trees less than 12 inches in diameter, pruned to a height of eight feet, and poles and support structures less than 12 inches in diameter) shall exist between a height of 2½ feet and eight feet above the upper face of the nearest curb, or street centerline if no curb exists, within the sight triangle.

The sight triangle itself is defined precisely: for a corner lot, it's the area bounded on two sides by the street right-of-way lines, each having a length of 25 feet, and a third side connecting the two right-of-way sides; for a driveway meeting a street, it's formed the same way, measuring 25 feet from the point where the right-of-way and the edge of the drive intersect. In practical terms, a solid privacy fence has to stay under 2½ feet or clear eight feet within that 25-foot triangle at every corner and driveway apron, though it can be any height elsewhere on the lot since Appendix A doesn't otherwise cap fence height.

The rule sits inside the landscape standards article, which also lets the planning director accept an existing natural buffer in place of required plantings elsewhere on a lot, but that substitution doesn't reach the sight-triangle restriction. Because Appendix A attaches to Chapter 38, it applies only in the zoned areas of unincorporated Oconee County the county council has mapped, not the unmapped Control Free District, and road design sight-distance standards are separately governed by Chapter 32's Unified Performance Standards.
